Many tuners have attempted single turbo setups on the BMW N54 direct injected turbo 6. Up to this point, nobody has been able to come to market with a reliable solution. HPF announced they intended to provide a single turbo kit for the N54 last year. They seem to be progressing further than anyone else and making it into a reality. Expect dyno numbers to come soon but for now the details we have are that this kit will be able to run any Precision T4 Turbo from a 67 to a 76.

Additionally, HPF is aiming for a starting price of $5950 which will include the turbo manifold, journal bearing Precision turbo, wastegate, oil scavenge pump and hardware, downpipe, intake charge pipe, motor mount, motor mount relocation kit, VBrace, fittings, couplers, etc. This will really shift the N54 turbo upgrade options and be incredibly competitive. After this is released expect a Stage II with fueling upgrade but that is further down the line.

Engineers come and go and with the money they make they can hire anyone they really want. Even better people really...

Plus if they had no tuners/engineers how exactly would they come up with the RHD turbo kit they did?

You obviously have no sense of what it costs to employ a real engineer.. Adapting an existing e46 m3 kit to RHD really isn't too hard to do and did not require any "engineering". They simply fabricated new exhaust manifolds/intakes and used the rest of their parts and engine management (with a few tweaks to an existing tune) from the original kit, that a real engineer created.

With their 335i turbo kit, they had a local fabricator (note I said fabricator, not engineer) make an exhaust manifold for them. The difference in approach, when compared to their e46 kit, was vastly different and it showed in the end product.

Ya dude what did was super easy which is why nobody else is selling the same thing right?

I'm sure you love talking about how easy things are on paper that they are doing as if you are an expert in what HPF does or does not do as if you work there.

And from my days on e90post, most 335 owners strike me as unwilling to drop the necessary coin to buy a HPF product. They spend it all on ridiculous wheels instead. And a ST requires a lot of other mods to make it decent to drive.

This, the mods needed to make a E92 N54 handle on par with the power running FBO+Meth+E85 made me sell it and get a platform more suitable. Even with the Bilstein/Eibach kit the rear was always to loose, and I guess one need at least sway bars+LSD+the diff lock down kit+solid rear bushings to solve that. I used that money as a down payment instead and I'm 100% certain I got more "performance" out of the money spend that way.

Let's not forget that hpf accepted a customer's car what, 4 years ago with the intention of pursuing the n54 which they were hoping was its next big money maker. I know you're wondering how i know that but logic dictates you dont borrow someone's car for three years unless you have a specific business tactic.

To act like hpf is infallable is foolish, look at apple, the mighty are falling all over the place, reputation only buys you so much, you can't live off the reputation of Steve jobs forever, you need to constantly advance or risk becoming a one hit wonder.

Now go ahead sticky and give me my negative thumbs for making a logical comment.

That's kind of my point; one that you're horribly missing. This is a discussion about THIS platform, not the S54 or any other BMW engine.

OMG OH NO HPF didn't do what I wanted when I wanted for my motor and instead has big hp on a different motor. They are failures. Cry cry cry baby.

My goals? No. I assumed THEIR goal was to market a viable single turbo kit for the N54. Did they do that? No. So it was a failure. Not a failure to meet my goals, but a failure to meet theirs. I already described WHY it happened, you can go back and read if you want.

Who said I was crying about it? You're the one making such a big deal here. Is HPF run by your best friend or something? You're sitting here complaining about people being righteously annoyed at HPF. No one is saying they should be barred from making products, or that their existing products suck, or that the owners are terrible people and should die.

Oh come off it; I couldn't give a $#@! if they were $#@!ting gold bricks out their ass. They still failed. Claim it's money, claim it's stubborness, claim it's the mood of their lead that day; that is all MOOT, it is outside the scope, it is not pertinent, it is an ex-parrot (had to go the full Python skit there). Stick to the point here instead of casting my points (and others) as some piss-poor straw man and then arguing with that instead.

HPF made a business decision and will sell a tried and true manifold and tuning solution. They already do one platform better than anyone. It isn't their responsibility to push multiple motors in this economy.

Ya, doing millions of dollars in revenue and being one of the biggest BMW engine builders and tuners out there. What a screw up!

Did I say they were a screw-up as a company? You're implying I did, but I did not. Please don't put words in my mouth, thanks. Again all of what you said is irrelevant. You want to actually argue here, or are you going to continue to rant and rave about random unrelated $#@! again?

It doesn't take a rocket scientist to design a turbo kit or manifold. If you know or can figure out a handful of parameters you can design tuned headers with a few simple high school physics formula's, and turbo manifolds are way simpler. I've made plenty of homemade systems. As long as you plan it out, measure, and have knowledge of turbo systems and the car you can put together some kickass hardware. A couple people here have done just that...

Whatever reason they backed out of the N54 wasn't because of hardware, or lack of an epic engineer to design it, or anything like that. It was either financial or tuning related, or a combination thereof, regardless if you believe tuning is their job or not. A $6,000 kit with no dyno numbers won't sell, or they believe it wont, because at that point it's not a kit it's simply a box of parts that can be had cheaper if you do it yourself. Pre turbo O2, post turbo O2, these things make very little difference when designing the manifold, but huge differences for tuning and reliability. I remember them working on a port setup to try to address the stock fuel system, which went nowhere that I know of but shows they put in some pretty major efforts to work out a tune on their own. It's not their job to give you guys a play by play, especially if learning cost them a lot that they will not be able to recoup. Pick up a phone and called them or drive out to visit them if you really want an answer, but it doesn't matter in the scope of things. The forums aren't the end all be all to information, and nobody is required to post anything, many do not. Everyone arguing on this page has some sort of complex, be it "N54 is holier than thou", or "I'm holier than thou". Give it up already, yeesh.

I apologize for resurrecting this page, now can it die already?

I agree with nearly all of your points. But two things to keep in mind: No one is saying the forums are the be all to information and nobody is saying HPF is REQUIRED to post anything. I have no idea where anyone got that idea. They're free to do stupid $#@! all they want just as we're free to ridicule them for it.

No tuner is perfect. The almighty Shiv has had a ton of things go wrong and so what?

That's kind of my point; one that you're horribly missing. This is a discussion about THIS platform, not the S54 or any other BMW engine.

And I keep trying to tell you the point that you are horribly missing which is HPF made their name with another motor and their success on it is what is driving demand for them to pursue the N54. Their shop is filled with E46 M3's, ok?

They haven't failed in anything as they haven't sold you anything. Where their development is at is their business. IT'S THEIR BUSINESS. So they are making the best business decisions for themselves. Let Vishnu and others work the kinks out while they sell their kits they already developed.

Maybe you should read my interview with Chris and see his comments on the N54. It isn't his focus. You and others are acting like the N54 should be.

Running a successful BMW tuning business is failing just because they don't devote everything to your motor? Right.

Saying they failed when they aren't even finished yet is essentially saying they screwed up. Yep.
